To? AEnorLANE.

To all whom it may concern Be it known that I, CORNELIs WANDERS, a I citizen of the United States, residing at Okaton, in the county of Lyman and State of South Dakota, have invented new and useful Improvements in Toy Aeroplanes, of which the following is a specification.

This invention relates to toy aeroplanes of that type adapted to be flexibly suspended from an overhead support and to be propelled in a determined path permitted by said support through the action of suitable propelling means.

One object of the invention is to provide a toy aeroplane of the character defined which may be economically manufactured, and which permits of the use of a comparatively weak spring motor for the purpose of transmitting motion to the propeller.

A further object of the invention is to provide a construction of body, planesor wings, and bracket or frame support for the motor, whereby economy of manufacture is insured.

The invention consistsofthe featuresof construction, combination and arrangement of parts herein fully described and claimed, reference being had to the accompanying drawings in which Figure l is a side elevation showing the aeroplane suspended from an overhead support. Fig.2 is a top plan view of the same. Fig. 3 is a vertical longitudinal section through the center of the body. Fig. 4 is a vertical transverse section thereof. Fig. 5 is a perspective view of the bracket detached. Fig. 6 is a detail view on an enlarged scale showing a feature of construction of the bracket.

The device comprises an elongated body 1, of circular form vided with a pointed or other suitably shaped forward end 2. This body carries a pair of aeroplanes 3, arranged in following order, or one in rear of the other, and which may be suitably curved in a fore-and-aft direction for supporting effect. Each aeroplane comprises a longitudinal frame strip 4, preferably of thin resilient sheet metal, and a body or covering 5 of paper,-textile fabric or other suitable material. This covering 5 is composed of two or more folds of the material which are suitably secured together and which are also so folded as to'provide a pocket 6 for the reception of the frame strip, whereby the wings of each plane are supported in position. The central part of each in cross section, and protions 25 of the plate 11 Specification of Letters Patent. Patent d D 21 1915 Application fil ed June 22 915. Serial No. 35,610.

strip is fitted in a slit or recess 7 in the upper surface of the body 1, at an angle to the path of travel of the machine to dispose the plane at a proper angle of incidence, the strip being secured in position against displacement by a tack or other headed fasplane as a whole, which may be of some considerable weight in proportion to its size, 1n order to enable an inexpensive type of spring motor to be used.

The body 1 supports a car or motor frame 10 which consists of a pair of superposed plates 11 and 12, of sheet metal, which plates form bearings for the vertically disposed shaft 13 of a spring actuated motor, which shaft is provided with a winding key 14. The motor shaft is connected through the medium of a train of gearing 15 with a propeller shaft 16 extending horizontally in parallel relation with and beyond the rear end of the body and carrying a suitable form of propeller 17. The plate 11 is connected by upright pieces 18 to a semi-circular saddle 19 which forms a seat for and receives the body 1 and is secured thereto by suitable fastenings 20. The upright pieces 18 are preferably formed with a saddle 19 of a single piece of sheet metal and are bent downwardly from the saddle and soldered or otherwise fastened to the plate 11, which latter is formed at its ends with slots 21 and downwardly bent portions 22, which portions 22 depend on the outer sides of uprights 23 rising from the plate 12, which uprights have inwardly bent portions 24 dis posed in the slots 21 and between the portions 22 and resting upon horizontal porl8 said parts being firmly soldered or otherwise fastened together. This construction provides a simple and inexpensive type of frame for supporting the motor and fastening the same to the body 1 and which may be manufactured inexpensively, and will at beyond the uprights the same time permit'of the use of a simple type of spring motor.

In the use of the device, the free end of the suspending cord or cable is attached to a suitable overhead support and the winding key actuated to Wind the engendered and the compression of the airby the wings the aeroplane will rise and extend its orbit of travel to a maximum degree, and will take a gradually less extended course as the driving pressure weakens on the running down of the motor until it finally returns to a perpendicular or'plumb frame and driven by the motor, and a saddle position through the force of gravity. The operation may then be repeated by rewinding the motor, and by rewinding it from time to time the aeroplane mav be kept in constant flight.

The principal advantage of my invention resides in the fact that it may not only be inexpensively made, but will give sufficient support so as to be driven through a circular 4 path of comparatively Wide diameter by the action of a comparatively weak motor, on

thus reducing the cost of refinement to secure diminished weight.

I claim 1. A toy aeroplane comprising a body,

propelling means supported thereby, said body having inclined recesses therein, and planes arranged in following order, and each consisting of wings provided with pockets and a metallic strip fitted in the pockets of the Wings on each plane, said strips being fittedwithin said inclined recesses, means for holding the strips seated in said recesses, and means for flexibly suspending the device from an overhead support.

2. A toy aeroplane comprising a longitudinally extending body, planes carried by the body, a frame, a spring motor carried by the frame, a propeller supported by the connected with said frame and forming a seat for the body, said saddle being suitably secured to the body.

In testimony whereof I aflix my signature in presence of two Witnesses.
